    "description": "To improve the security of Azure SignalR Service resource, ensure that it isn't exposed to the public internet and can only be accessed from a private endpoint. Disable the public network access property as described in https://aka.ms/asrs/networkacls. This option disables access from any public address space outside the Azure IP range, and denies all logins that match IP or virtual network-based firewall rules. This reduces data leakage risks.",
